<< If you reread the post he said that the drive grounded the relay in both

 the driver control logic so that it works.  One probably used A/C on was
 normally open contacts of the relay so that driver was on and the other
 one used normally closed contacts on the relay so that the driver was on
 to shut the A/C off.  So the question is were can a person change the
 logic on the A/C driver bit. >>

 So use a 5 pin bosch relay and in normal op its set to one contact, when 
energized it uses the other. But..no..I mista mised that :-(
